AUTOMATIC BELL-ALARM FOR ELEVATOR-CAGES.

fiPECIPICATION forming part of Letters Patent No. 356,461, dated January25,1887.

Application filed February 25,1886. Serial No. 193,182. (No model.)

To all whom it may concern.-

Be it known that we, JOHN HENRY FLAUGHER and ALVIN BROOKS Sco'rr, bothresidents of Manchester, in the county of Adams and State of Ohio, haveinvented certain new and useful Improvements in Automatic Bell-Alarmsfor Elevator-Cages; and we do hereby declare that the following is afull, clear, and exact description of the invention, which will'enableothers skilled in the art to which it appertains to make and use thesame,

reference being had to the accompanying d rawings, which form a part ofthis specification, and in which Figure l is a view of a portion of theshaft and cage of an elevator provided with our improved alarm. Fig. 2is a front view,on an enlarged scale,of the alarm and of theoperatingrollers. Fig. 3 is a vertical sectional view of the same. Fig.4 is a detail view showing a modified form of the projections foroperating the alarm.

Similar letters of reference indicate corresponding parts in all thefigures.

Our invention has relation to automatic alarms for elevator-cages, whichwill sound an alarm at every landing in the elevator-shaft, warningpersons in the cage and about the shaft of the approach of the cage; andit consists in the improved construction of parts of such an alarm, ashereinafter more fully describedand claimed.

In the accompanying drawings, the letter A indicates one of the siderails of the elevatorshaft which guide the cage, or an upright railsecured in the side of the shaft, and B indicates the bottom of thecage, having side pieces, 0.

A small casing or box, D, is formed in one corner of the bottom ofthefcage, having, preferably, perforated sides which will freely admitthe sound of the bell-alarm to pass out through them, and a bell, E, issupported within this casing upon a horizontal bar, F. This bell isprovided with a vertically-sliding rod, G, sliding through the top ofthe bell and having,-preferably,a knob, H, upon its upper end, and thisvertically-sliding rod is suitably connected with the hammer I, whichwill strike the side of the bell when the vertical rod is depressed.

An elbow-lever, J, is pivoted at its bend in the side of theelevator-casing, the outer side of which is formed with a verticalgroove or recess, I in which the downwardly-projecting arm K of theelbow-lever may rest. The inwardly-projecting arm M of the lever restsnormally with its end against the knob of the vertically-slidingoperating-rod, having, preferably, aprojecting lip, N, at that end,which will increase the weight of that arm and afford a larger surfacefor resting upon the knob. The downwardly-proj ecting arm of the leveris formed with an outwardly-bulging triangular portion,0,which projectsoutside of the groove or recess in which the arm rests.

The vertical rail at the side of the elevatorshaft is provided with oneor more transverse rollers, P, journaled between lips Q, secured uponthe rail, suitable spaces being between each roller, and these rollersare secured to the rail at every landing or hatchway of theelevator-shaft, and may engage the bulged portion of the elbow-lever asthe cage passes the rollers.

If desired, the number of rollers may correspond to the number of thestory at which attached, so that the bell will indicate at which storyof the building, in which the elevator is, the cage has arrived.

In the way ofa modification,instead of constructing the device foroperating the alarm with rollers adapted to engage the bulged portion ofthe elbow-lever, the vertical rail at the side of the elevat0r-shaft maybe provided with projecting triggers made of leather or other flexiblematerial, as shown at S. The projecting part. of these triggers wouldactuate the elbow-lever in precisely the same manner as the rollers, andbeing flexible they will yield to the passage ofthe car up and d0wn,soas not to interfere with the smooth working of the same.

' The bell may be constructed, as shown in the drawings and asdescribed,with the verticallysliding rod passing through the top of thesame, but this construction being found in a number of other bells andbeing old it follows that any other suitable construction of bell may beused in which the inner weighted arm of the elbow-lever will sound thebell, this construction being, however, preferable on account of itssimplicity and efficiency.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States- 1. In combination with a verticalrail in an elevator-shaft and an elevator-cage, an alarm consisting ofprojections upon the vertical rail, a bell, and a lever pivoted in thesideof the elevator-cage, the outer end of said lever adapted to engagesaid prqjections,and the inner end being weighted to operate the hammerof said bell, as and for the purpose shown and set forth.

2. In an elevator,the combination of rollers journaled upon the face ofa vertical rail in the elevatorshaft at the landings, an elbowleverpivoted in the side of the elevator-cage and having a downwardlyprojecting arm 'formedwith a bulging portion and an inner weighted arm,and a bell having its operating-rod below the end of the weighted arm,asand for the purpose shown and set forth.

3. In an elevator, the combination of rollers journaled upon the face ofa vertical rail in the elevator-shaft, an elbow-lever pivoted at itsbend in the side of the cage and having its JOHN HENRY FLAUGIIER. ALVINBROOKS SCOTT.
